In early 2012 an intriguing single-board computer with a weird name hit the market. For the low price of $35, you could get a fully functioning computer that could run a real operating system.

It was called the Raspberry Pi and it was the brainchild of a UK charity called the Raspberry Pi Foundation. They saw the need for an affordable computer after seeing a consistent drop in students applying to study computer science.

Well it turns out this tiny and cheap fully-functional computer had a much larger audience than anticipated. Multiple models have been created since, including the $5 Pi Zero, and over 5 million Raspberry Pis have been sold.

This is a long post so I more than likely made some errors along the way. Feel free to let me know on Twitter, thanks!
